JOHN D. RIVELY, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF TWO- THIRDS TO LOUIS F. WENTZ AND JAMES D. IRONS, OF SAME PLACE.

ELECTROTH ERAPEUTIC SYRING E.

SPECIFICATION forming-part of Letters Patent No. 578,611, dated. March 9, 1897.

Application filed April 24:, 1896- To a. whom it may concern:

Be it known that 1, JOHN D. RIVELY, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered a new and useful Improvement in Therapeutic Electrodes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this application, in Which Figure 1 is a view in elevation, illustrating my invention as applied to a fountain-syringe. Fig. 2 is a detail view illustrating a different form of external contact. Fig. 3 is an enlarged sectional detail view showing the method of construction for securing electrical communication through the nozzle of a syringe, constituting internal contact.

Similar numerals of reference refer to like parts wherever used throughout this specification.

My invention relates to combined electric and douche devices for applying at the same time electric therapeutic action by means of and in connection with internal liquid application.

It consists of the special construction and combination hereinafter shown.

Referring now to-the drawings, 2 is a battery or other source of electrical energy, communicating with the positive and negative poles of which are the wires 3 4, the wire 4 being attached to a conducting-handle 5, or, as illustrated in Fig. 2, to a plate 6 of any desired or preferred form.

7 is the reservoir of a fountain-syringe, to the end of the rubber tube 8 of which is at tached a tubular coupling 9, provided with r a binding-post attachment 10, in which is se- Serial No. 588,875. (No model.)

a wire 14, projecting through the interior of the tube 11 and terminating slightly Within the socket in said casting, the socket being sufficiently enlarged to permit of easy passage of the fluid contents of the reservoir 7 and yet confine the end of said wire and hold the same centrally in the pipe 11. When thus constructed, it will be seen that when the nozzle of the syringe is inserted in the usual way and the handle 5 grasped by the user, or the plate 6 placed against the body,

the circuit will be closed, as indicated by the dotted line 15.

The nozzle 13 may be made of metal, such as brass, aluminium, or silver, if desired, although it is not necessary that it shall be an electrical conductor, inasmuch as the stream of water or other liquid passing through it will serve to establish an electric circuit, so that the ordinary rubber nozzle commonly employed may be used with equally good results. The wire 14 also serves to stiffen the section of tubing 11, whereby it may be more readily directed by the operator.

The advantages of my invention will be appreciated by those skilled in the art, as it combines the features of merit set forth in a marked degree, and is, furthermore, very efficient, simple, and cheap and can be operated and used by any person unfamiliar with electrical devices.

What I claim is-- In combination, a bulb, a flexible pipe leading therefrom, a second flexible pipe, a metallic sleeve between them carrying a binding-post, a casting in the end of the second pipe, a detachable nozzle thereon, a conduit leading therethrough, a socket in the end of the casting, and a wire extending through the second pipe into the socket and electrical connections, substantially as described.

In testimony whereof I have hereunto set my hand this 18th day of April, 1896.

. JOHN D. RIVELY.
